The last two Type56's that I worked on shot 320-ish. They might have been "original" versions. Both of them took a good pounding to get apart (i.e. blocks of wood and pounding with a hammer)...and to put back together. I was very, very impressed with the build.
Not as impressed with the setup of the internals (parts were good-ok...shimming was poor). Freaking mechbox edges were sharp enough to draw blood. With a little loving, the mechbox sings.
Aside from the shimming, the stupid rubber bayonet, and the absolutely tiny space in the stock...they're awesome. They shoot smooth as silk. By far one of the best AEG AK's I've handled.
